Johnny and Jon were an influential American folk duo active in the late 1960s and early 1970s. Known for their harmonious vocals and acoustic guitar-based instrumentation, their music blended elements of traditional folk, country, and blues. The duo, consisting of Johnny Hartman and Jon Anderson, gained prominence for their socially conscious lyrics and emotive storytelling. Their seminal album, "Songs from the Heartland," is often regarded as a significant contribution to the folk music revival of the era.
